L'opinione del pilota.

"I flew the two actual aircraft which were involved in 9/11... Fight number 175 and Flight 93, the 757 that allegedly went down in Shanksville and Flight 175 is the aircraft that's alleged to have hit the South Tower. I don't believe it's possible for... a so-called terrorist to train on a 172, then jump in a cockpit of a 757-767 class cockpit, and vertical navigate the aircraft, lateral navigate the aircraft, and fly the airplane at speeds exceeding it's design limit speed by well over 100 knots, make high-speed high-banked turns,.. pulling probably 5, 6, 7 G's... I couldn't do it and I'm absolutely positive they couldn't do it.", Russ Wittenberg - ex pilota dell'Air Force che ha volato con gli United Airlines Flight 175 e 93, due dei quattro Boeing dirottati l'11 settembre.
